[0084] In order to make the purpose, technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be described clearly and completely in the following in conjunction with the accompanying drawings of the embodiments of the present disclosure. It should be noted that the dimensions and shapes of the figures in the accompanying drawings do not reflect the true proportions, but are only intended to illustrate the contents of the present disclosure. Moreover, the same or similar symbols throughout indicate the same or similar components or components having the same or similar functions. Obviously, the described embodiments are some, but not all, of the embodiments of the present disclosure. Based on the described embodiments of the present disclosure, all other embodiments obtained by a person of ordinary skill in the art without the need for creative labor are within the protection scope of the present disclosure.

[0085] Unless otherwise defined, technical or scientific terms used herein shall have their ordinary meaning understood by a person of ordinary skill in the art to which the invention belongs. “First”, “second” and similar words used in the description and the claims of the invention do not indicate any order, quantity or importance, but are only used to distinguish different components. Words such as “include” or “comprise” mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects. Words such as “inside”, “outside”, “up”, “down” are only used to express relative positional relationships. When the absolute position of the described object is changed, the relative positional relationship may also be changed accordingly.

[0086] The word “about” or “substantially the same” as used herein includes a value stated and means being within an acceptable deviation range relative to a specific value as determined by those of ordinary skill in the art in view of the measurement discussed and errors (i.e. limitations of a measurement system) associated with the measurement of a specific quantity. For example, “substantially the same” can mean that a difference from the value stated is within one or more standard deviation ranges or within ranges of ±30%, 20%, 10%, or 5%.

[0087] In the accompanying drawings, the thicknesses of layers, films, panels, regions, etc. are enlarged for the sake of clarity. The illustrative implementations are described herein with reference to sectional views that serve as schematic diagrams of the idealized implementations. In this way, deviations from shapes of the figures will be expected as a result of, for example, manufacturing techniques and / or tolerances. Therefore, the implementations described herein should not be interpreted as being limited to the specific shapes of regions shown herein, but rather include deviations in shapes resulting from, for example, manufacturing. For example, regions illustrated or described as flat regions can typically have rough and / or nonlinear features. In addition, the sharp corners illustrated can be rounded. Therefore, the regions shown in the figures are illustrative in nature, and their shapes are neither intended to illustrate the precise shapes of the regions shown, nor intended to limit the scope of the claims.

[0088] In order to keep the following description of embodiments of the present disclosure clear and concise, the present disclosure omits detailed descriptions of well-known functions and components.

[0089] The liquid crystal cell is the core of the liquid crystal display, and the display effect of the liquid crystal display is mainly influenced by the liquid crystal cell. The main parameters of the liquid crystal cell include transmittance, contrast, viewing angle, response time, drive voltage, etc. Here, the response time represents the time required for the liquid crystal cell to switch between bright (white) and dark (black) states, driven by a pixel voltage, when the torque of the external electric field overcomes the resistance generated by the elastic coefficient, viscosity, and other factors of liquid crystal molecules. The longer the response time, the easier it is for the human eye to observe the phenomenon of image trailing.

[0090] In previous designs, OD (overdrive) technology was used to solve the problem of too long response time. However, the response time of liquid crystal molecules is easily affected by temperature, especially negative liquid crystal molecules. When the ambient temperature of liquid crystal molecules changes, the response time will also change. At this time, the OD setting parameters cannot correspond to the response time after the temperature changes, this may cause problems in the display of the screen. When the temperature decreases, the deflection speed of the liquid crystal molecules becomes slower, the original OD function cannot be satisfied, and the image appears poor tailing. When the temperature rises, the deflection speed of the liquid crystal molecules becomes faster, the original OD function is excessive, and the image appears negative color trailing.

[0091] In view of this, embodiments of the present disclosure provide a display panel, as shown in FIG. 1, which has a display area AA and a plurality of fan-shaped routing areas F on one side of the display area AA, where the display panel includes:

[0092] a plurality of gate lines 1, extending in a first direction X, and in the display area AA;

[0093] a plurality of data lines 2, extending in a second direction Y, intersecting with the gate lines 1, and in the display area AA;

[0094] a plurality of routing groups Z, where at least one of the plurality of routing groups Z is located in at least one of the plurality of fan-shaped routing areas F. Specifically, the fan-shaped routing area F corresponds to the routing group Z in one-to-one correspondence, and one routing group Z is arranged in one fan-shaped routing area F. At least part of the routing group(s) Z is electrically connected with the data line(s) 2. The routing group includes multiple routings. The routings in the routing group are electrically connected with the data lines to provide data signals for the data lines; and

[0095] at least one temperature sensor 3, on a same side of the display area AA as the fan-shaped routing areas F, where at least part of the temperature sensor(s) 3 is in an area between two adjacent fan-shaped routing areas F;

[0096] where the temperature sensor 3 is configured to detect an ambient temperature, so that the display panel loads a voltage on the data lines 2 based on a temperature detected by the temperature sensor 3.

[0097] Specifically, when the temperature detected by the temperature sensor 3 is within a first threshold (which can be a temperature range lower than a room temperature), the voltage applied to the data line 2 is greater than a voltage applied at the same gray scale at the room temperature, so as to accelerate the deflection speed of the liquid crystal and avoid poor tailing. When the temperature detected is within a second threshold (which can be a temperature range higher than the room temperature), the voltage applied to the data line 2 is less than the voltage applied at the same gray scale at the room temperature, so as to slow down the deflection speed of the liquid crystal and avoid poor anti-tailing. Specifically, a table of relationships between temperatures and gray scales can be stored in the display device, for example, a first storage table corresponding to the first threshold, a second storage table corresponding to the second threshold, and a third storage table corresponding to the room temperature can be stored, so that when the temperature is detected to be within the first threshold, a voltage can be loaded to the data line 2 according to the first storage table; when the temperature is detected to be within the second threshold, a voltage can be loaded to the data line 2 according to the second storage table; when the temperature is detected to be within the room temperature range, a voltage is applied to the data line 2 according to the third storage table. Specifically, the first threshold can correspond to a temperature lower than the room temperature, and the second threshold can correspond to a temperature higher than the room temperature. Specifically, in a possible embodiment, the first storage table can be an OD parameter table set according to low temperature, the second storage table can be an OD parameter table set according to high temperature, and the third storage table can be an OD parameter table corresponding to the room temperature. The OD parameter table includes grey scale values of the previous frame and the confirmed over drive grey scale values corresponding to the grey scale of the current frame. For example, the grey scale of the previous frame includes 0, 8, 16, 24, 32, 40, 48, . . . , 240, 248, 255 grey scales (7 grey scales per interval, of course, other interval grey scales can also be set, which is not limited here); the gray scale of the current frame includes 0, 8, 16, 24, 32, 40, 48, . . . , 240, 248, 255 grayscale (7 grey scales per interval, of course, other interval grey scales can also be set, which is not limited here). For example, if the gray scale of the previous frame is 32 and the gray scale of the current frame is 64, the corresponding gray scale of the OD gray scale table is 84 (the gray scale of the current frame is greater than the gray scale of the previous frame, and the OD gray scale can be greater than the gray scale of the current frame). For example, if the gray scale of the previous frame is 168 and the gray scale of the current frame is 40, the corresponding gray scale of the OD gray scale table is 38 (the gray scale of the current frame is smaller than the gray scale of the previous frame, and the OD gray scale can be smaller than the gray scale of the current frame). The gray scale of the current frame is equal to the gray scale of the previous frame, and the OD gray scale can be equal to the gray scale of the current frame. It should be noted that in this case, multiple OD parameter tables can be stored, and different OD parameter tables can be called according to different temperatures or temperature ranges, so as to provide the data signals for the data lines in the display area. Of course, only two OD parameter tables can be stored, that is, two versions of parameter tables corresponding to the high temperature (such as 50~60° C.) and the low temperature (−40~−30° C.), the parameter tables corresponding to other temperatures are generated based on the measured temperature, the high and low temperature parameter tables, which can reduce the storage of the storage tables.

[0098] In embodiments of the disclosure, the display panel is provided with the temperature sensor 3 on the side where the fan-shaped routing area F is located. The display panel loads the voltage on the data line 2 according to the temperature detected by the temperature sensor 3, so that when the temperature detected by the temperature sensor 3 is lower or higher, the OD tables corresponding to different temperatures are called to ensure that the liquid crystal molecules maintain the same (normal) deflection speed at different temperatures, so that the display panel can adjust the OD parameters in real time according to the change of ambient temperature to ensure the normal display of the screen, so as to solve the problem of OD function failure caused by temperature change and ensure the working performance of the display panel at different temperatures. In addition, compared to setting the temperature sensor 3 on other sides of the display panel, in embodiments of the present disclosure, the temperature sensor 3 is located on the side of the display panel where the fan-shaped routing area F is located, which can avoid the possibility of weak signals detected by the temperature sensor 3. If it is set in an area far from the side where the circuit board is bound to the fan-shaped routing area F, a longer routing will affect the strength of the detected signal, leading to the problem of inaccurate signals. In addition, the temperature sensor 3 is located on the side of the display panel where the fan-shaped routing area F is located, which has little impact on the internal routing of the display panel. And, the routing space between the fan-shaped routing areas of the display panel is large. When the common routing is set in the area between the fan-shaped routings, the common routing can be adjusted to set the temperature sensor. Due to the relatively large area of common routing compared to other display signal lines, adjusting the common routings to set sensors to give new functions to the display panel will not have a significant impact on the signal of the common routing and will not affect the display effect. This can ensure normal display while giving new functions to the display panel, improving display quality.

[0099] In a possible embodiment, as shown in FIG. 1, FIG. 2A to FIG. 2E, where FIG. 2A is an enlarged schematic diagram of the temperature sensor 3 in FIG. 1; FIG. 2B is an equivalent circuit diagram of FIG. 2A; FIG. 2C is a schematic diagram of a single film of the first electrode portion in FIG. 2A; FIG. 2D is a schematic diagram of a single film of the active portion in FIG. 2A; FIG. 2E is a schematic diagram of a single film of the second electrode portion in FIG. 2A. The display panel includes the array substrate P1 and the opposite substrate P2 arranged opposite to each other, and the temperature sensor 3 is located on the array substrate P1. The array substrate P1 is provided with a first substrate 10, and the temperature sensor 3 includes a first electrode portion 31, an active portion 32 located on the side of the first electrode portion 31 facing away from the first substrate 10, and a second electrode portion 33 located on the side of the active portion 32 facing away from the first electrode portion 31. The orthographic projection of the first electrode portion 31 on the first substrate 10 covers an orthographic projection of the active portion 32 on the first substrate 10, and the orthographic projection of the active portion 32 on the first substrate 10 covers an orthographic projection of at least part of the second electrode portion 33 on the first substrate 10. Specifically, a control signal can be loaded onto the first routing 41 electrically connected with the first electrode portion 31, and a signal corresponding to the temperature can be obtained according to the detected signal between the second routing 42 and the third routing 43 electrically connected with the second electrode portion 33.

[0100] Specifically, as shown in FIG. 1, on the side where the fan-shaped routing area F is located, the temperature sensor 3 can be specifically set in the area between the outer edge of the display area AA and the outer edge of the opposite substrate P2.

[0101] In a possible embodiment, as shown in FIG. 1, FIG. 2A to FIG. 2E, the second electrode portion 33 includes: a first sub-portion 331 and a second sub-portion 332 disposed opposite to each other; the first sub-portion 331 includes: a first main portion 3311 extending in the first direction, and a plurality of first branch portions 3312 extending out from the first main portion 3311 in the second direction Y; the second sub-portion 332 includes: a second main portion 3321 extending in the first direction X, and a plurality of second branch portions 3322 extending out from the second main portion 3321 in the second direction Y; and the first branch portion(s) 3312 intersects with the second branch portion(s) 3322.

[0102] Specifically, as shown in FIG. 2A and FIG. 2B, the temperature sensor 3 can be a transistor, the first electrode portion 31 can be used as the control electrode TG, the first sub-portion 331 can be used as the first electrode TD of the transistor, and the second sub-portion 332 can be used as the second electrode TS of the transistor. The first electrode portion 31 can control the opening or closing of the temperature sensor 3, and by measuring the current signal between the first sub-portion 331 and the second sub-portion 332, the relevant signal detected by the temperature sensor 3 can be obtained. Specifically, the first electrode portion 31 of the temperature sensor 3 can be made of the gate layer metal, the active portion 32 can be made of the semiconductor active layer, and the second electrode portion 33 can be made of the data line layer metal, forming the gate electrode (TG), source electrode (TS), and drain electrode (TD) of the temperature sensor. The channel width-to-length ratio (W / L) of the transistor can be 2500 / 3.9 (it can be adjusted according to the materials used, design scheme and other factors). In order to increase the detection accuracy of the sensor, the width-to-length ratio of the transistor in the sensor is larger than the width-to-length ratio of the transistor in the display area of the display panel. The transistors in the display area are used to realize electrical connection with the gate line, the data line and the pixel electrode of the display panel. Optionally, in this case, in order to simplify the process, the transistors within the display area, transistors contained in temperature sensors, or transistors contained in light sensors are prepared using the same process, that is, the transistor in the display area and the sensor between the fan-shaped routing areas are prepared with the same layer and the same material.

[0103] In a possible embodiment, as shown in FIG. 1, FIG. 3A to FIG. 3E, where FIG. 3A is an enlarged schematic diagram of the temperature sensor 3 in FIG. 1; FIG. 3B is an equivalent circuit diagram corresponding to FIG. 3A; FIG. 3C is a schematic diagram of a single film of the first electrode portion in FIG. 3A; FIG. 3D is a schematic diagram of a single film of the active portion in FIG. 3A; FIG. 3E is a schematic diagram of a single film of the second electrode portion in FIG. 3A. The at least one temperature sensor 3 includes: two first electrode portions 31 arranged in the first direction X, two active portions 32 arranged in the first direction X, and two second electrode portions 33 arranged in the first direction X; the two first electrode portions 31 are spaced apart and independent of each other; the two active portions 32 are spaced apart and independent of each other; the two second electrode portions 33 share a same first main portion 3331, and the second main portions 3321 of the two second electrode portions 33 are spaced apart and independent of each other. In embodiments of the disclosure, the temperature sensor 3 adopts a dual transistor structure; and the structure composition and process parameters of the two transistors can be completely consistent. Two transistors use the same first main portion 3331, and the first electrode portion 31 and the second main portion 3321 are used independently. In the specific implementation, as shown in FIG. 3B, only one of the transistors can be set to be in a normal working state, and its three terminal electrodes can be set with appropriate voltage according to the situation (for example, TG1=−8V, TS=0V, TD1=15V), and the other transistor is not working, the voltage condition can be set to TG2=TD2=TS, ensuring that the three terminal potentials are the same, and avoiding characteristic drift. The two transistors periodically switch operating states based on usage time to avoid characteristic drift caused by long-term operation, increase the service life of temperature sensors, and improve the detection accuracy of temperature sensors.

[0104] Specifically, as shown in FIG. 3F, FIG. 3F shows a transition curve of the temperature sensor as a function of temperature. When the ambient temperature rises from −20° C. to 60° C., the increase of the on-state current Ion is not obvious, while the increase of the off-state current Ioff is obvious. The off-state current Ioff is more sensitive to temperature changes, but the off-state current Ioff value is small, it is not easy to be detected and is vulnerable to noise. The off-state current Ioff or on-state current Ion can be selected as the detection signal of the temperature sensor according to the specific situation.

In this way, the problem of OD function failure caused by temperature change can be reduced, and the performance of the display panel at different temperatures can be guaranteed without increasing the production process of the display panel.

[0116] In a possible embodiment, as shown in FIG. 3A-FIG. 3E and FIG. 5, the data lines 2 are disposed on one sides of the gate lines 1 facing away from the first substrate 10; the display panel includes: a pixel electrode and / or a common electrode disposed on one sides of the data lines 2 facing away from the gate lines 1; the first electrode portion 31 is of a same layer and a same material as the gate line 1; the second electrode portion 33 is of a same layer and a same material as the data line 2; the first adapter portion 51 and the second adapter portion 52 are of a same layer and a same material as the pixel electrode layer or common electrode.

[0117] Specifically, as shown in FIG. 5, the gate insulation layer GI can be provided between the gate line 1 and data line 2, the passivation layer PVX can be provided between the data line 2 and the pixel electrode and / or common electrode, the first sub-hole K110 and the third sub-hole K210 can penetrate through the passivation layer PVX; the second sub-hole K120 and the fourth sub-hole K220 can penetrate through the passivation layer PVX and the gate insulation layer GI.

[0118] In a possible embodiment, as shown in FIG. 6, FIG. 6 can be an enlarged schematic diagram of FIG. 4 at dotted circle S2. At least one of the second sub-routing portion 422 and the fourth sub-routing portion 432 has a plurality of hollow areas P0. In embodiments of the present disclosure, since the second sub-routing portion 422 and the fourth sub-routing portion 432 are located in the outer area of the display area AA, this area is covered by the frame sealant. The second sub-routing portion 422 and the fourth sub-routing portion 432 are provided with a plurality of hollow areas P0, so that the ultraviolet light for curing the frame sealant can pass through the second sub-routing portion 422 and the fourth sub-routing portion 432, in order to avoid the problem that the frame sealant cannot be cured normally by ultraviolet light.

[0119] In a possible embodiment, as shown in FIG. 6, the common routing 6 is provided with a first hollow portion P1, at least part of the common routing 6 is in an area between two adjacent fan-shaped routing areas F; an orthographic projection of the temperature sensor 3 on the first substrate 10 is in an orthographic projection of the first hollow portion P1 on the first substrate 10. In embodiments of the present disclosure, the temperature sensor 3 is arranged at the first hollow portion P1 of the common routing 6, which can make the common routing 6 compact with the temperature sensor 3, and is conducive to the uniformity of metal lithography at this location.

[0120] In a possible embodiment, as shown in FIG. 6, the common routing 6 is further provided with a plurality of second hollow portions P2, an area of the first hollow portions P1 is larger than an area of the second hollow portion P2; and the common routing 6 is of a same layer and a same material as the first electrode portions 31.

[0121] In a possible embodiment, as shown in FIG. 7, FIG. 7 can be an enlarged schematic diagram of FIG. 4 at dotted circle S1, the routing group Z includes a plurality of leads Z1; a distance d1 between adjacent sensor leads 4 is 1.5 to 5 times of a distance d2 between adjacent leads Z1. Since there are many leads in the fan-shaped routing area, in order to reduce the width of the frame, the density of the leads will be set higher, and the line distance will be smaller on the premise of ensuring the stability of the process, for example, 3 μm~8 μm. The line width d3 of the sensor lead 4 is 5 to 10 times of the line width d4 of the lead Z1. Specifically, the distance d2 between adjacent leads Z1 in the routing group Z can be 3 μm~8 μm. Specifically, for example, it can be 3 μm, 4 μm, 5 am, 5.3 μm, 6 μm, 7 μm, 8 μm. The distance d1 between the sensor leads 4 and the distance between the signal lines of the gate drive circuit (such as the clock signal line) can be equal. The signal line of the gate drive circuit extends longer in the non-display area. For example, the clock signal line transmits an AC signal, so the signal lines will be coupled with each other. The distance between the clock signal lines cannot be closer when the non-display frame is reduced. Since the sensor leads need to detect or feedback signals to avoid coupling effects between signal lines, the distance between the sensor leads and the distance between the signal lines of the gate drive circuit can be consistent. Specifically, the distance d1 between the sensor leads 4 can be 10 μm~20 μm. Specifically, for example, it can be 10 μm, 11 μm, 15 μm, 16 μm, 17 μm, 18 μm, 20 μm.

[0122] In a possible embodiment, as shown in FIG. 1 and FIG. 3A to FIG. 3E, a shape of an orthographic projection of the active portion 32 on the first substrate 10 is a rectangle. Specifically, the shape of the orthographic projection of the active portion 32 on the first substrate 10 is a square, that is, the side length of the active portion 32 along the first direction X is equal to the side length of the active portion 32 along the second direction Y. In embodiments of the present disclosure, the shape of the orthographic projection of the active portion 32 on the first substrate 10 is a rectangle, which can make the temperature sensor can be square as a whole, and it is difficult to observe from the outside. When the temperature sensor is rectangular, if there is no black matrix obstruction, due to the reflection of the metal layer, bright strips may be observed from the outside.

[0123] In a possible embodiment, as shown in FIG. 1, FIG. 3A to FIG. 3E, a shape of an orthographic projection of the first electrode portion 31 on the first substrate 10 is a rectangle. Specifically, the shape of the orthographic projection of the first electrode portion 31 on the first substrate 10 is a square, that is, the side length of the first electrode portion 31 along the first direction X is equal to the side length of the first electrode portion 31 along the second direction Y. In this way, the temperature sensor can be square as a whole, which is difficult to be observed from the outside. When the shape of the temperature sensor is rectangular, a more obvious bright strip can be observed from the outside.

[0124] In a possible embodiment, as shown in FIG. 8, the display panel also includes at least one light sensor 7, where the light sensor 7 is on the same side of the display area AA as the fan-shaped routing area F, and the light sensor 7 is in an area outside of the fan-shaped routing area F; and the light sensor 7 is configured to detect brightness to adjust brightness of the display panel based on detected brightness. Referring to FIG. 8, it is shown that the light sensor 7 and the temperature sensor 3 are respectively set between different fan-shaped routing areas, or both can be set between adjacent fan-shaped routing areas, that is, the light sensor 7 and the temperature sensor 3 are both set in the corresponding area of the temperature sensor 3 in FIG. 8, which is not limited here.

[0125] In a possible embodiment, as shown in FIG. 9A to FIG. 9E, where FIG. 9B is a schematic diagram of a single film of the first electrode portion in FIG. 9A; FIG. 9C is a schematic diagram of a single film of the active portion in FIG. 9A; FIG. 9D is a schematic diagram of a single film of the second electrode portion in FIG. 9A; FIG. 9E is a schematic diagram of a single film of the black matrix layer in FIG. 9A. The structure of the light sensor 7 is the same as that of the temperature sensor 3, this can simplify the preparation process and make the display panel compatible with the temperature detection and the light detection. In addition, in the case of that the structure of the light sensor is the same as that of the temperature sensor, it can also be used as a temperature sensor when temperature detection is required, and as a light sensor when light brightness detection is required, that is, the temperature sensor is compatible with the light sensor, enabling the production of two different functional devices in one process. Optionally, the temperature sensor and the light sensor can both be set at a corresponding position between two adjacent fan-shaped routing areas, or they can be set at different positions between two adjacent fan-shaped routing areas. In this case, both the temperature sensor and the light sensor are set in the display panel. Through simple preparation process, the panel can be compatible with two functions, improving the display quality and the integration of the display panel.

[0126] Specifically, the structure of the light sensor 7 is the same as that of the temperature sensor 3. The structure of light sensor 7 can be completely consistent with the composition of the film layer, the pattern shape of each film layer, and the process parameters of the temperature sensor 3. Of course, in specific implementation, the structure of the light sensor 7 can also be partially different from the composition of the film layer and the pattern shape of each film layer of the temperature sensor 3. Specifically, for example, as shown in FIG. 9A and FIG. 9B, the first electrode portion 31 of the two sub-light sensors 71 can be an integrated communication structure.

[0127] In a possible embodiment, as shown in FIG. 9A to FIG. 9E, the light sensor 7 includes two sub-light sensors 70; the display panel further includes a black matrix layer 8, where the black matrix layer 8 is provided with a first black matrix opening 81, an orthographic projection of a sub-light sensor 70 of the light sensor 7 on the first substrate 10 is within the first black matrix opening 81, and the other of the sub-light sensors 71 is obscured by the black matrix layer 8. In embodiments of the present disclosure, the light sensor 7 also adopts a dual transistor structure, and the process parameters of the two transistors are completely consistent with the temperature sensor. One of the sub-light sensors 71 is not covered by the black matrix (that is, it is located in the area where the first black matrix opening 81 is located), that is, one of the sub-light sensors 71 can be exposed to ambient light, and the other sub-light sensor 71 cannot be exposed to ambient light, and the external light intensity is measured by the brightness difference between the two. In this case, the black matrix can be set on the opposite substrate which is opposite to the array substrate, or on one side of the array substrate, which is not limited here.

[0128] In a possible embodiment, as shown in FIG. 9A, a shape of an outer contour of the active portion in the sub-light sensor 71 is square. In this way, the bright strip problem caused by the reflection of the metal layer in the area without black matrix cover can be avoided.

[0129] Specifically, as shown in FIG. 10A, specifically, FIG. 10A can be the equivalent circuit diagram of FIG. 9A. The sub-light sensor 71 is a three terminal field-effect transistor structure, and the three terminals are PS, PG, and PD. The two sub-light sensors 71 use the same PS and PG electrodes, and the PD electrodes are used independently.

[0130] Specifically, as shown in FIG. 10B, the characteristics of the light sensor change with the light. When the ambient light changes from darkness to 5000 nit, the increase of the on-state current Ion is not obvious, and the increase of the off-state current Ioff is obvious. The off-state current Ioff is more sensitive to the changes of ambient light, but the current value is small and difficult to capture. During normal operation, PG can be set to −8V (the point where the light sensor is most sensitive to light can be adjusted according to the external driving circuit conditions, and the point where the sensor is most sensitive to light under different process conditions may be different). PS can be set to 0V, PD1 and PD2 can be set to 15V. After being illuminated by the ambient light, the current value of the sub-light sensor 71 at the first black matrix opening 81 increases compared to the sub light sensor 71 at the obstruction of the black matrix, and the increase value is proportional to the light intensity. The current difference between PD1 and PD2 is taken as the reference value under the ambient light condition to adjust the backlight brightness.

[0131] In a possible embodiment, as shown in FIG. 11, the display panel has a first symmetry axis k1; the first symmetry axis k1 passes through a center of the at least one temperature sensor 3.

In embodiments of the present disclosure, in addition to the temperature sensor 3 on the side where the fan-shaped routing area F is located, the temperature sensors 3 are also set in the first side area B1, the second side area B2, and the third side area B3, which can effectively improve the detection accuracy. Especially for large size display products, the temperatures at different locations may have large differences.

[0133] In a possible embodiment, the first electrode portion 31 of at least one of the temperature sensor 3 and the light sensor 7 is configured to load a square wave signal to turn on the temperature sensor 3 at intervals of a preset length of time, and / or to turn on the light sensor 7 at intervals of a preset length of time. Specifically, the first electrode portion of the temperature sensor 3 or the first electrode portion of the light sensor 7 is loaded with a square wave (AC) signal, which means that temperature sensor 3 or light sensor 7 is turned on at a preset interval of time, such as 10 seconds, to prevent the transistor from being turned on continuously, causing drift of the temperature sensor 3 and the light sensor 7. The square wave signal, for example, is a PWM signal.

[0134] Specifically, the display area AA can be provided with a pixel circuit, which can include a pixel circuit transistor. The film layers of the temperature sensor 3 and the light sensor 7, and can be made in the same layer and process as the corresponding film layers of the pixel circuit transistor.

[0135] Based on the same inventive concept, embodiments of the present disclosure also provide a display device, including the display panel provided in embodiments of the present disclosure.

Specifically, the first circuit board C1 can be a printed circuit board (PCB), and the first processor D1 can be an operational amplifier (OP) to amplify, add and subtract, and perform differential operations on the signals detected by the temperature sensor 3 or the light sensor 7. For example, differential operations can be performed on the signals received by the two sub-sensors 71 in the light sensor 7 to obtain the external light signals detected after removing interference from other factors.

[0137] In a possible embodiment, as shown in FIG. 1, FIG. 8 and FIG. 11, the display device further includes a second circuit board C2 on the side of the first circuit board C1 far away from the display panel and electrically connected with the first circuit board C1;

[0138] the second circuit board C2 includes: a second processor D2 configured to process the first signal to form the second signal; the display device further includes a third processor D3, wherein the third processor D3 at least stores a first storage table corresponding to the room temperature, a second storage table corresponding to the first threshold, and a third storage table corresponding to the second threshold; the third processor D3 is configured to call the first storage table, the second storage table or the third storage table based on the second signal to load voltage to the data lines according to the grayscales of the first storage table, the second storage table or the third storage table.

[0139] Specifically, the second circuit board C2 can be a logic board. The second processor D2 can be a microcontroller unit (MCU), and the third processor D3 can be a logical processor TCON. The temperature sensor 3 converts the captured temperature signal into a specific target value through MCU, and sends it to the TCON through the 12C line to call the corresponding OD table, and the signal acquisition mode is in-phase proportional amplification.

The fourth processor D4 can be an LED Driver. Specifically, the fourth processor D4 can be electrically connected with the second processor D2, and connected with the interface of the backlight source of the display panel. The light sensor transmits the received light signal to the MCU processing unit through OP, and the MCU sends the processed target signal to the BLU to adjust the backlight brightness.

[0142] The display panel of embodiments of the present disclosure is different from the traditional display panel with OD function. The integrated design of the temperature sensor of the display panel cooperates with OD adjustment, which can ensure the normal display of the panel under high / low temperature conditions and improve the stability of the panel. Different from the conventional external temperature sensor, the temperature sensor of the display panel in embodiments of the present disclosure is integrated inside the display panel, and does not occupy additional space or increase the panel volume. The temperature sensor adopts the bottom gate thin-film transistor structure, which is compatible with the conventional LCD panel process and does not require additional photolithography.
